CASTING-MACHHHE. I

Application filed September 12, 1916. Serial No. 119,630.

To all whom it may concern Be it known that I; PAUL D. WRIGHT, a resident of Wilkinsburg, Allegheny county, Pennsylvania, and a citizen of the United States, have invented certain new and useful Improvements in Casting-Machines, of which the following is a specification.

My invention aims to provide certain improvements in casting machines, such for example as pig iron or other metal casting machines, whereby such machines are made safer and more economical in time and labor.

The accompanying drawings illustrate an embodiment of the invention.

Figure 1 is a side elevation of a pig casting machine of known type with my improvements applied thereto. Fig. 2 is a cross-section on the line 22. Fig. 3 is a cross-section on the line 33.

An endless chain of molds A fastened together by links B travels along mold-guid ing top rails C and bottom rails D, each mold having rollers E on its ends running onsaid rails. The chain of molds travels in the direction of the arrows, being driven by end sprockets F and G. A chute H pours hot metal (or whatever material is to be molded) into the molds at a rate proportioned to their feed. They are carried along so far and so slowly that the castings therein have hardened by the time they reach the discharge end and the molds are then inverted to dump the castings, say into a chute J and a car K.

It sometimes happens that a casting will not fall out of its mold but will stick therein till the mold has passed the proper discharge point and then will fall out at any undetermined point in the usually great length of the chain. Such stickers are heavy and usually hot and exceedingly dangerous, and much labor and time are lost in getting them into the cars. I propose to guide such stickers to a bin or other place where they can be easily collected and handled.

To prevent uncontrolled dropping of stickers there are, in the machine illustrated, supplementary rails L and 0 located beneath the return path of the molds, these rails extending parallel to the mold-support- Specification of Letters Patent.

ing rails D and being located close to the mouths of the inverted molds,so that any stickers falling out of such molds will be caught on said supplementary rails. Preferably the space is such, see Fig. 3, that the stickers X will not escape entirely from the molds but will be loosely engaged thereby. The molds will 'thus aid in guiding the stickers and willpush them along the supplementary rails. The rails L obviously may be made of any desired length and the bin N positioned at the end of the rails L as shown in Fig. 1, in such case the rails 0 being dispensed with.

Though I have described with great particularity of detail a specific machine embodying my invention, yet it is not to be understood therefrom that the invention is restricted to the particular machine described. Various modifications indetail and in the arrangement of the parts and adaptations thereof to other casting or molding machines may be made by those skilled in the art, without departing from the invention.

What I claim is 1. A casting machine comprising a traveling series of molds and supports located'beneath the return path of the molds to support any castings which may be carried past the discharge point of the machine.

2. A casting machine comprising a traveling series of molds and supports located beneath the return path of the molds to support any castings which may be carried past the discharge point of the machine, said supports being located close to the mouths of the molds so that castings falling on to said supports will be conveyed along the supports by the molds. I

3. A casting machine comprising a traveling series of molds and adapted normally to dump their castings at a certain discharge point and means for preventin castings which are carried past said point rom being discharged except at a second determined point.

4. A castin machine comprising afiexible chain of 11101 s, mold guiding rails and supplementary rails located beneath the return path of said chain of molds and parallel to the first-mentioned rails.

5. A casting machine comprising a flexible chain of molds, mold guiding rails and sup- )lementary rails located beneath the return vath of said chain of molds and parallel to 1e first-mentioned rails, said supplementary rails terminating at a point intermediate in the length of the chain of molds, so as to drop at that point any castings carried 10 thereon.

In witness whereof I have hereunto signed
